Wheel Adaptor to spacer conversion

[Mothy]

By changing to steel wheel nuts instead of the standard enclosed alloy nuts I have discovered that I do not get enough thread engagement when I fit my after market rims - looks like the mounting surface is slightly thicker than the one on the standard rims. (my standard rims are fine)

I use 1" adaptors on the front and 2" at the rear so I believe I have 2 options:
a) install slightly longer studs in the adaptors
or
b) press out the old adaptor studs, and install much longer studs in the hub, using the old (studless) adaptor as a spacer.

Has anyone done a) or b) before?

We are only talking about a couple of mm here but its enough to fail scrutineering at a track day.

Check out this thread from a few years back on how to replace wheel studs for longer ones if you want to use wheel spacers. I'm going to do this myself.
